Charlson Comorbidity Index: A Critical Review of Clinimetric Properties

🤖 Plain-English Summary

The present critical review was conducted to evaluate the clinimetric properties of the Charlson Comorbidity Index (CCI), an assessment tool designed specifically to predict long-term mortality, with regard to its reliability, concurrent validity, sensitivity, incremental and predictive validity. It may also predict in-hospital mortality, although in some instances, such as ICU or trauma patients, the CCI did not perform as well as other instruments designed specifically for that purpose.

🔑 Key Findings

• The original version of the CCI has been adapted for use with different sources of data, ICD-9 and ICD-10 codes.
• The inter-rater reliability of the CCI was found to be excellent, with extremely high agreement between self-report and medical charts.
• The CCI has also been shown either to have concurrent validity with a number of other prognostic scales or to result in concordant predictions.
